You can't parallel standard power transistors because of the thermal characteristsics
It depends on how you connect them. I run 4 power transistors in parallel for one of my projects. The collectors are connected to the supply rail. Between the emittor of each transistor and ground I have a small value resistor. If a transistor gets hot and starts trying to conduct more, then the voltage drop across the resistor increases. This reduces gain of the transistor and stops it from working so hard. This stops 1 transistor from trying to do all the work and destory itself with thermal runaway.
Yup...next thing you know...they'll try to quit paying you for after hours work.
This is what some places in Australia do.
Instead of being payed overtime you are given time off. Time Of In Lieu (toil). Finding time to make use of accumated toil is not that easy without upsetting someone. A cap is placed on how much toil a person can have at anyone time. Anything above that cap is lost. The end result is the boss getting unpaid overtime from the workers.
I had a pair of 486 laptops I wanted to install a minimal system on to use them as X terminals
and
I'd build the system in a chrooted environment on my destop and then tarball the sucker.
Wouldn't it have given you a smaller image if you done
ROOT=/tmp/image emerge X plus whatever else is needed
Should give an image for a X terminal with out the added bloat of a development system in the image. You don't need much of an image for an X terminal.
Sometimes the interference is the equiment not a crappy signal from the amateur radio operator. With your amp it could have been a number of things including lack of filtering for frequencies above the audio so it did not stay an audio only amp and the leads between components acting as antennas.
Had a vcr that went stupid every anytime there was a transmittor nearby. Amateur or otherwise. Only vcr I have had a problem with. The problem was fixed using 2 x 15 cent capacitors and 3 coils made from hookup wire wound a around a pencil. A simple filter and the problem was fixed. The problem was fixed using 30 cents (retail price) worth of parts.
Neighour complaing of tvi problems. The feed line to his tv antenna had broken and needed to be replaced. Still blamed me.
Powered computer speakers acting as a radio receiver. Speakers should not act as radio receivers. If a speaker acts as a radio receiver there is something wrong with the speaker. At least it should be easy to fix.
My favourite. Another neighour complainng of tvi even when all my radios are turned off. Their problem was a very bad reception area for the tv channel they were trying to watch. A better tv antenna fixed the problem.
I can under stand why he might have been an ass. Not excusing it because he should not have been. But if you receive enough complaints and it is mostly because of shody comsumer goods or the people are just clueless it is easy to become a bit cynical.
I think someone who gives deodorant and underpants for a present is lacking a bit of imagination. Even the book on making paper planes that I received is more interesting.
We know different people. The linux people I know dual boot with their legitimate copy of windows to play games which they also acquired legally.
It is the windows people that I know run their pirate copy of windows and frequent warez site for their software needs.
Personally I don't understand why so many people think telemarketing is such a big deal.
Their timing for one. I resent having a telemarketer call after I have sat down and started eating the evening meal. Guaranteed they won't make a sale.
The only problem I have had with pdf files generated this way was when I used ps2pdf and the fonts looked horrible when viewed with adobe. So far have not had a problem using pdflatex.
To deal with the font problem when using ps2pdf I use \usepackage{times}. Abode pdf reader is then happy.
The other way I have of making pdf files is to have a printer defined (I use the HPLJ4 driver) and set it to output to a postscript file. Then use ps2pdf to convert it to pdf. Have had good results with that. Also means any application that can print can generate a pdf.
Only about 4 weeks ago. A group having a contact on 14.187. Another station starts up on 14.185 then promply complains about the interference from a nearby frequency. The people on 14.187 also had interference from the new station on 14.185. Then someone else starts up on 14.191 was overdriving the audio into his radio. His transmission on 14.191 was nearly 9kHz wide and causing a lot of interference. Not bad for a ssb signal. These were american radio amateurs.
Existing conversation on 7.060, non english stations. Some australian amateurs started talking on this frequency. The overseas stations were stong enough they the australian amateurs could not even hear each other yet they stayed on the same frequency. This was also 3 - 4 weeks ago.
These are on the hf bands where you need the higher licences. I am not sure about the american licences for these 2 bands but in australia you need the highest amateur licence. The morse did not seem to do a good job of keeping those kind of people of the hf bands.
80m can even be worse. I have heard stuff there that would have been right at home on 27MHz cb. Another band where morse is needed to access.
It still begs the question on why a doctor has gone to the movies in the first place when on call.
If the theater advertises that mobile phones won't work this would mean the doctor is knowing going into an area where he is out of contact while on call.
The distance the radio signals travel are part of why the hf bands are used for comms.
I live in the south east corner of Queensland Australia. Depending on the frequency and time of day a signal can easily travell around the world. By listening on the 7MHz and 14MHz bands it is generally easy to find someone in Europe, the US or other places around the world.
From what I have read BPL has the potential to cause interence anywhere in the world by varying degrees because the frequencies travell so far.
I recently had a phone from one of my hieghbours because he was getting a lot of interference on his tv. Even though I said I had not been using the radios and they were not even connected he still thought I was the cause of the interence. He had heard I had transmitting equipment so immediately though it was me.
After making wait him while I unpacked everything I needed to make my radios work we conducted some test and he was finally convinced I was not the cause of the interference. Even telling him that the radio gear was not even capable of being used at the time was not enough for him to think that someone/something else was to blame.
People resent being blamed for something that was not their fault even when the blame continues after his has been shown there is no way it could have been them.
That depends on where you live. Where I am in Australia part of the backbone is still 1200 baud.
Using anything irc like is ok for example the talk mode on the local X1J4 node or a convers server on a NOS system is useable. Reading your mail or bulletins on the other hand is not something that you would to download and try reading in real time. It is more like download them and read later when the forward session has finally finished. Browsing web pages at this speed is not fun.
At these kind of speeds something like what is mentioned in the article could be usefull. But by the time you get up to 56k or so my preference would be just use google.
I stopped using my ink jet printer becuase I got sick of buying new black cartridges. They have an intergrated print head. After having 3 die I changed to a laser printer. I only ever seemed to be able to refill them 2 time before the print head would die.
The cartridges cost $65AU. There was recently advertised a lexmark for $50AU. In this case a new printer would have cost less then a replacement cartridge for my old printer.

I am using a 5w 0.1ohm resistor on each emittor. Peak current is between 15 - 20 amps. Average is a bit over 5 amps.

I am not sure which dd stands for. Just searching on google I found some references say disk dump and others saying data dump.
I don't know if it is correct or not but the first thing that comes to mind is disk dump.
I have been using Open Office 1.1.0. The export to pdf button is imediately to the left of the printer icon on the top toolbar.
It is quite a usefull feature. Something that gets missed whenever I have to use word for something.
If a peson knows the brakes are defective and drives the car anyway they should be at fault.
Trying co.uk might return an error but put a www in front of it and try again. Seems to belong to someone.

In place of Master/Slave, we could use Primary/Secondary - an acceptable substitution.
That would make my drives
1st hd - primary primary
2nd hd - seconday primary
burner - secondary seconday
But where does that leave my floppy?

At last these mice can not climb into a computer and pee on the motherboard. Nothing like forced upgrades.
It is not a good filter.
